Panko is a type of breadcrumb used in Japanese cuisine, known for its light and airy texture. Unlike traditional breadcrumbs, panko is made from crustless bread that is coarsely ground, resulting in larger flakes. This unique texture allows it to create a crispier coating when fried or baked, making it a popular choice for dishes like tonkatsu and tempura. Panko can be found in most grocery stores and is often used as a topping for casseroles or as a filler in meatballs and meatloaf. It is versatile and can be seasoned to enhance the flavor of various dishes, making it a staple in many kitchens.
